I have a Samsung SyncMaster 2233RZ monitor which can do real 120 hz. When using the fglrx driver with my Radeon 4850, i can choose between 60, 100, 110 and 120 hz. However, when using the radeon driver, i can only select 60 hz.
Here's the xrandr output:
Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 1680 x 1680
HDMI-0 disconnected (normal left inverted right x axis y axis)
VGA-0 disconnected (normal left inverted right x axis y axis)
DVI-0 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 478mm x 300mm
1680x1050 59.9*+
I'm using Ubuntu 9.10.
